Comparison of sampling pattern and plot dimensions, to estimate the percentage of crown cover and forage production in plant communities with different distribution patterns (Study area: Choghakhor Rangelands Chaharmahal and Bakhtiari province, Iran)

Jamal Imani; Ataollah Ebrahimi; Bahram Gholinejad; Pejman Tahmasebi

Volume 28, Issue 4 , November 2021, , Pages 640-651

Abstract
        In the present study, we compared different sampling patterns and different plot dimensions to estimate the percentage of canopy cover and forage production in rangeland habitats around Choghakhor Wetland. The choice of sampling method was based on the opinion of the researcher. ...  Read More

Application of remote sensing information to estimate production and plant cover percentage(Study area: Rangelands around Choghakhor Wetland in Chaharmahal and Bakhtiari Province)

Jamal Imani; Ataollah Ebrahimi; Bahram Gholinejad; Pejman Tahmasebi

Volume 28, Issue 3 , October 2021, , Pages 450-471

Abstract
  The present study was conducted to investigate the differences between several remote sensing indices, four different plot sizes and two different sampling methods to estimate the percentage of plant cover and production in three plant communities in 2013. Ground sampling was performed in three communities ...  Read More

Comparison of NDVI and SAVI in three plant communities with different sampling intensity (Case Study: Choghakhour Lake Rangelands in Charmahal & Bakhtiri)

Jamal Imani; Ataollah Ebrahimi; Bahram Gholonejad; Pezhman Tahmasebi

Volume 25, Issue 1 , April 2018, , Pages 152-169

Abstract
      Identifying and evaluating rangeland ecosystems is the first step in managing these resources. Without knowledge of rangeland condition, no management plan can be developed for it. For this purpose, three sites with different dominant species were selected for sampling. In each site, ...  Read More

Comparison ground samples establishing, number and areas in Landsat 8, 30×30 pixels to aware correlation plant cover percentage with NDVI index in three study areas (Study area: Rangelands around Choghakhor Dam Lake in Chaharmahal & Bakhtiari province)

Jamal Imani; Ataollah Ebrahimi; Pejman tahmasebi; Bahram Gholinejad

Volume 24, Issue 2 , July 2017, , Pages 429-440

Abstract
  The use of satellite data is one of the proper methods, which makes studying ecosystems less costly. This research was carried out to determine the correlation among the vegetation cover of dominant species in three sites with the NDVI index. For this purpose, a study was conducted on three different ...  Read More

Assessment of vegetation changes in rangelands under different grazing intensities Case study: Charandow of Kurdistan province

Jamal Imani; Ali Tavili; Esaa Bandak; Bahram Gholinejad

Volume 17, Issue 3 , October 2010, , Pages 393-401

Abstract
  Analysis of vegetation is one of the important factors in appropriate management of rangelands. The current research was conducted to evaluate canopy cover percentage, forage production, and species density in four areas including reference area, personal rangeland, key area and critical area in the ...  Read More

Assessment the effects of flood spreading on the variation of rangelands vegetation cover (In Mayhem watershed in Ghorveh, Kurdistan)

Jamal Emani; Ali Tavili; Essa Bandak; Mohammad Khosravi

Volume 17, Issue 2 , September 2010, , Pages 234-242

Abstract
  Flood water spreading projections have been done with many objectives. One of these objectives is increasing vegetation cover. Flood water spreading leads to the increasing of soil moisture and as a result increasing forage production. In this study the effects of flood spreading are evaluated. This ...  Read More
